This is an article taken from the New York times. It is a popular article however it is considered a very credible paper that has factual information. DENNIS OVERBYE I chose this article because it summarizes the basic idea's behind the new theory that gravity is not an actual force. After this article I learned what area's I will need more information on in order to prove my point. It is a very factual article and gives me very basic information.This article is summarizing the basic ideas of gravity being an illusion. They are summarizing works of a string theorist by the name of Dr. Erik Verlinde.
I. Gravity is an illusion A. Causing a ruckus among physicists because the theory is trying to reverse the last 300 years of physics.
II. Gravity is a result of the laws of thermodynamics. A. Entropy
III. but Dr. Verlinde is among a number of physicists who say that science has been looking at gravity the wrong way and that there is something more basic, from which gravity “emerges,” the way stock markets emerge from the collective behavior of individual investors or that elasticity emerges from the mechanics of atoms.
III. Major Problems in physics that could be solved by new theory. A. Dark Energy B. Dark Matter
IV. Bad Hair analogy A. Nature likes to take the path of least resistance. 1. Thats why hair curls because there are more options for hair to curl than there are for it to be straight.
V. Current theory is too complicated and leaves to many issues with current view of gravity.
VI. Paper is very confusing and some of the best scientists don't understand it however some believe that it makes a much better fit of our universe than the current model.
VII. Dr. Valinde Is known for his mastery of string theory mathematics and not for philosophical battles.
VIII. Over the last 30 years gravity has been taken apart. A. Even Einstein proved newtons equations wrong.
IX. Dr. Hawking discovered a connection between thermodynamics and black holes. A. Black holes should explode if quantum equations are applied to black holes.
X. Black holes are theorized with a holographic principle. A. 3-D images have the information but desplay the information above it. B. Black holes absorbe the information deep inside them but they are encoded on the surface. C. Mabey this idea applies to the universe as well and mabey we are all just images where we are really objects just being encoded in space.
XI. In one striking example of a holographic universe, Juan Maldacena of the Institute for Advanced Study constructed a mathematical model of a “soup can” universe, where what happened inside the can, including gravity, is encoded in the label on the outside of the can, where there was no gravity, as well as one less spatial dimension. If dimensions don’t matter and gravity doesn’t matter, how real can they be? (direct quote)
XII. Entropy is causing gravity. A. Gravity is no longer a fundamental force
XIII. Dr. Padmanabhan said that he could see little difference between Dr. Verlinde’s and Dr. Jacobson’s papers and that the new element of an entropic force lacked mathematical rigor. “I doubt whether these ideas will stand the test of time,” he wrote in an e-mail message from India. Dr. Jacobson said he couldn’t make sense of it
Quote: But what if it’s all an illusion, a sort of cosmic frill, or a side effect of something else going on at deeper levels of reality?
Seven Things that Don't make Sense about Gravity
I chose this article because it outlines the basic problems with the current view of the force of gravity. It will help add data to the side that gravity is a fake force. It is a popular article but it seems to be based in just facts and not to much analysis so there is not too much room for biases.
I. What is gravity? A. Einstien changed almost all of the fundamental ideas about gravity.
II. Why does gravity only pull? A. Every other force attracts and repels.
III. Why is gravity so week A. Compared to the other fundamental forces gravity is unbelievable week and doesn't attract very much.
IV. Why is gravity fine tuned? A. With gravity being just a little bit weaker or stronger life could not exist.
V. Quantum Mechanics and Relativity A. Two theories that are at great odds with each other also have both been proven to work. B. Very different view of the universe at very small and very large than to our perspective.
Gravity: Seven Unanswered Questions about Natures most Familier Force
I chose this article because it goes into more details about the article above. The article, Seven Things that Dont make Sense about Gravity, just briefly outlines the major problems and gives a good base into what I have to reaserch more. Gravity: Seven Unanswered Questions about Natures most Familiar Force gives explanations and much more information to back up the previous article. It is very credible. It is taken from a scientific magazine and cites many leading scientists from various universities.
A.You jump up, and gravity brings you back down to Earth. You reach the brow of a hill and gravity accelerates you down the other side. All neat and tidy then: gravity behaves in the way Newton thought of it, as a force that affects and changes the motion of something else. (Quote)
B. Einsteins view Changed Everything 1. Curvature of Space Time 2. The four dimensions of space-time 3. Newton said it is what one mass does to another but Einstein said it is what one mass does to the surroundings.
C. Although We have an idea where it comes from We dont know how the different parts come together to create gravity. 1. Mass 2. Energy 3. Space Time
D. Four Fundamental Forces 1. The Electromagnetic Force 2. The strong Nueclear Force 3. The Week Nuclear Force 4. Gravity
E. We know how the other three forces work. 1. We know what causes them and what transfers the force. 2. Operate with particles so then so should gravity a. es. Electromagnetic force is applied with photons
F. The problem 1. If we assume gravity works with particles it makes the most basic of questions unbelievable complex when talking about gravity. 2. There is absolutely no proof that there is such a gravity particle.
II. Why does Gravity only Pull?
A. The other fundamental forces have opposites. 1. Ex. Electromagnetic force can attract and repel based on what the charges are. a. Proton and electron attract while proton and proton repel.
B. The particles that transfer the other forces can be postive or negative
C. The "gravitron" 1. Theoretical particle that transfers gravity. 2. Responds to density which is always positive.
D. Quote Or are we assuming too much here? "We don't know that gravity is strictly an attractive force," cautions Paul Wesson of the University of Waterloo in Ontario, Canada. He points to the "dark energy" that seems to be accelerating the expansion of the universe, and suggests it may indicate that gravity can work both ways. Some physicists speculate that dark energy could be a repulsive gravitational force that only acts over large scales."There is precedent for such behaviour in a fundamental force," Wesson says. "The strong nuclear force is attractive at some distances and repulsive at others."
III. Why is gravity so weak
A. Compated to the other fundamental forces it is very weak.
B. The other three relative to distance away and size and charge of particle have about the same amount of push and pull where as gravity is much much weaker.
A New View of Gravity
I chose this article because it gives alot of details about the idea of gravity not being a real force. It is very understandable and doesn't go into a lot of crazy mathematics. It gives a very in depth but still easy to understand. This is a very credible article. It comes from a credible scholarly magazine.

I chose this article because it gives analysis on Eric Valendis new theory. It talks about what makes it credible and what makes it not. This comes from a scientific magazine so you know the information is correct.
